Chapter 228 Bathtub Hot Spring and Fire Dragon Air Conditioner

The productivity and scientific literacy in this world may be weak, but the absolute authority of lords over their territories ensures that Liszt can work with great efficiency.

After Marcus transported the volcanic glass ore back, Liszt quickly had the Flower Caravan invite the crystal craftsman Brad to start polishing these pieces of volcanic glass.

He then began his experiments.

First was the release and collection of fire dragon magic.

How to release the magic from the bubbles within the volcanic glass ore—after discussions with Gort and Marcus, they decided to use a drilling method. This involved drilling holes into the bubbles of the volcanic glass, allowing the internal fire dragon magic to be released without breaking the glass. The drilling task was assigned to Brad, who was unaware of the purpose.

Once the fire dragon magic was released, it gathered to form an invisible, small fire dragon.

The next step was to collect this magical fire dragon and inject it into a vessel carved from volcanic glass. Liszt gave instructions, and Brad executed them. Since the carving did not need to be intricate, the work progressed swiftly, thanks to Brad's skilled hands.

Irregular pieces of volcanic glass were transformed into various shapes under his carving. These parts were then assembled, and the gaps filled with volcanic glass powder to create a watertight glass container—a cylindrical jar about the thickness of an arm, known as a Fire Dragon Jar.

To test the seal of these Fire Dragon Jars, Liszt deliberately released a bit of fire dragon magic inside one.

He sealed the jar.

Not a trace of fire dragon magic leaked out. The properties of volcanic glass suppressed the magic, preventing it from coalescing or escaping.

"Next is to fill the jars with magic for energy use." Liszt followed the steps and handed the design of a glass apparatus to Brad.

Brad stared at it for a long time, unable to understand: "Sir Baron, what is this? Could you explain it in more detail?"

"Can't you see? It's a large syringe. See the outer cylinder? That's the barrel. The long rod with a cap at the front is the plunger. The plunger and barrel must fit tightly together so that when you press the plunger, the contents of the syringe can be ejected through the needle at the front."

No one here used syringes, so it took Brad considerable effort to understand the structure of the large syringe designed by Liszt.

Next came the carving and assembly to complete the large syringe.

The largest piece of volcanic glass was only basketball-sized, so the syringe required many pieces to be joined together. Brad, with years of experience in crystal carving, found the softer volcanic glass easy to work with, and he completed the large syringe in two days using a snap-fit assembly method.

Liszt took the large syringe and began the next experiment.

He aligned the barrel of the syringe with the half-human-sized magical fire dragon and pushed it down. As the magical fire dragon dispersed, some of its magic entered the syringe. He quickly covered the plunger, creating a "filled" syringe of fire dragon magic.

Inserting the needle through a round hole into the Fire Dragon Jar, he pushed the plunger, compressing the magic inside the syringe and injecting it into the jar.

A little fire dragon magic seeped out from the seams.

But most of the magic successfully entered the Fire Dragon Jar.

Repeating this process, he soon filled three Fire Dragon Jars with all the released fire dragon magic. In the vision of the Magic Eye, the fire dragon magic in the jars glowed red, transitioning to gold, indicating it had reached its limit.

A rough estimate showed that one ton of volcanic glass ore could release enough fire dragon magic to fill two Fire Dragon Jars.

The volcanic glass ore brought by Marcus weighed about six tons, so it could fill twelve Fire Dragon Jars: "Brad, make twenty of these standard jars, five larger ones, and twenty smaller ones."

Twelve standard Fire Dragon Jars would be used to contain the fire dragon magic, with the remaining eight as spares.

The five larger and twenty smaller Fire Dragon Jars were also kept as spares.

He gestured to the large syringe, which, like the Fire Dragon Jars, was actually called a Fire Dragon Syringe: "Additionally, make two more of these large syringes and two smaller ones."

...

Brad continued making the glass containers.

Liszt, meanwhile, continued his research on fire dragon magic. With the Fire Dragon Syringes and Fire Dragon Jars, he could freely move, divide, and recover the magical fire dragons.

Through his studies, he found that a palm-sized magical fire dragon was sufficient to boil a bathtub full of cold water.

A half-palm-sized magical fire dragon could keep a bathtub of water at forty degrees Celsius in a freezing environment, perfect for a bath. However, since the bathtub and hot water tank were separate, placing a slightly larger half-palm-sized magical fire dragon in the hot water tank yielded the best results.

After five days of work, the castle successfully had a hot spring bathtub. On the first night, Liszt soaked in the bathtub for over an hour.

He only left the hot spring bathtub reluctantly when he felt almost dehydrated.

Loosening the valve of the hot water tank, the hot water flowed continuously, collected by servants in buckets. The leftover bathwater could be carried downstairs for the servants to use...

Opening the bathroom window and the lid of the hot water tank, Liszt let the small magical fire dragon fly freely inside. The heating ability of the magical fire dragon was not strong, so even if left unattended, it wouldn't burn the bathroom.

Moreover, he placed a tiny magical fire dragon in a box in his bedroom, acting like a heater to maintain a comfortable temperature of around 24-25 degrees Celsius. He also placed a bowl of water to prevent dryness, making the entire bedroom warm and cozy.

A Fire Dragon brand constant temperature air conditioner.

"Mr. Carter, these boxes have been enchanted with magic arrays. Tell the castle servants not to touch them carelessly and to only clean the outside of the boxes when dusting."

"Understood, my lord."

Admiring his work over the past few days, he couldn't help but feel a sense of accomplishment: "The modernization of the castle has made initial progress. We have lighting, air conditioning, and a heat lamp... If we could get the magic of an ice dragon, we could make a refrigerator. If we could get the magic of a wind dragon, we could make a fan..."

Thinking of the wind dragon, he suddenly remembered that the Wind Roaring Valley in the Eternal Light Empire contained wind dragon magic.

"I wonder if volcanic glass can contain the magic of a wind dragon?"

Unfortunately, the Eternal Light Empire was on the other side of the continent, and even riding a Black Dragon horse would take about half a year.

Besides, he didn't know where else there might be residual dragon magic. Dragons probably only leave behind magic when they die or bleed. An invisible dragon that passed through Flower Town and ate two cows left behind only a spatial gem, no magic.

Thus,

With the hot spring bathtub built, the next task was to construct two bathhouses.
